To all whom t may concern: f

Be it known that I, JAMES L. MOORE, of Wellsville, in the-coiuity of Allegany,and

in the State of New York, have invented a' without using buckets or blades of extreme length involving structural weakness and inecient use of steam, especially in the last stage of the steam expansion in the turbine. A further object of my invention is to provide a construction of this character in which the steam follows the same general path of movement, that is to say, without reversing the direction of movement of the steam. A further object is -to avoid the use of more than one packing gland to seal the vacuum against atmospheric pressure thus avoiding the disadvantages inherent in previous dou-v ble-flow. turbines in which there'were two such glands necessary, one at each end of the shaft. A further object is to s o arrange the parts that the portion of the apparatus provided for the low pressure stage is in the form of a section which may be readily combined with the other sections used in the turbine.

While my invention is capable of embodiment in many different forms, for the purpose of illustration, I shall show only one orm thereof in the accompanying drawings, in which, Y

The figure is a longitudinal section of a turbine made in accordance with my invention, the same being shown somewhat diagrammatically. I

In the drawings I have shown a turbine which may be of any suitable type, but which is preferably of the multi-pressure stage impulse type, and this Aturbine may, for example, have a base 1 containing an oil chamber 2, and an oil pump 3. Upon the base 1 there are supported end frames 4 `and 5, which carry a turbine shaft 6 in anysuitable bearings. A governor 7 controls the speed of the turbine. A steam inlet chamber 8 is located at the high pressure end of the turbine, the same admitting steam in successionto a plurality of the nozzles 9 in diaphragme 9a, so as to cause the steam to imingel upon a series of wheels 10 having uckets 11. At the other end of the turbine, in order to utilize with the fullest effect the expansion ofthe steam, there is provided a by-pass passageway 12, which leads from a chamber 13 directly in advance of a wheel 14, said by-pass leading to Aa chamber 15 in a section 16 having nozzles 17 which dire@ the steam against a wheel 18 having buckets 19. The end section 23 of the turbine casing, which incloses the above named passages, wheels and chambers, is provided with lugs 9A upon its inner face with which engage bolts 25, thus securing the end or low pressure stage section detachably in position. The steam from the chamber l5 is discharged into an annular chamber 20, which communicates with an outlet pipe 21, in the basel. The steam from the chamber 13 which operates upon the wheel 14 is discharged into an annular chamber Q2, which also conmiunicates directly with the outlet pipe 21. In this way the steam which reaches'A the steam while, at the same time, the direction of the steam always forwardly direction. In this ei'ect of the steam tageous manner.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of my invention.
